PSYB64H3 Lecture Notes - Lecture 2: Central Nervous System, Lumbar Vertebrae, Pia Mater
Document Summary
Anatomical directions: rostral or anterior, head end of four legged animal, caudal or posterior, tail end of four legged animal. Inferior or ventral: towards the belly, superior or dorsal, towards the back. Some important structures of the brainstem: reticular formation, sleep and arousal, temperature regulation, motor control, medulla, regulation of breathing and heart rate, tissue damage in this area often fatal. The thalamus and hypothalamus of the diencephalon. The cortex: lobes of the cortex, localization of function in the cortex. Dienecephalon: thalamus, relay station, hypothalamus, sleep, arousal, temperature regulation, motor control, also controls pituitary gland (hormone secretion. Diseases of the basal ganglia: parkinson"s disease, progressive deterioration of dopamine-containing cells in the substantia nigra, huntington"s disease, progressive destruction of mainly the caudate and putamen. The cranial nerves: enter and exit the brain directly to serve the region of the head and neck.
